An air gap is to protect the potable water system from contamination from back syphon and it is the best protection possible as there is nothing mechanical to be tested or able to fail (Air gap water distribution) Air break drainage
Significantly-better cooling and insulation than air. This means that the transformer can operate at higher power ratings than an equivalent air-cooled transformer, and its internal electrical components can be much closer together, giving an oil transformer a much smaller footprint so it takes up far less space in a substation.
no.transformer coupling gives higher gain
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.

An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
Because of the presence of the air-gap between stator and rotor in motor the magnetization current is much higher than that of a transformer in addition to the friction and windage losses due to the rotation of the rotor.
This type of transformer is used on older type oil furnaces. It takes the 120 volt source and transforms it up to 15000 volts. This output wire is connected to the igniter which is an air gap device. The voltage is high enough to jump the air gap and produce a healthy spark. When the oil pump starts a mist of oil is pumped into the combustion chamber where it is ignited by the spark from the igniter.
The basic difference between the air cooled transformer and oil immersed transormer is: If the heat generated in the transformer winding is capable of being swapped by the sarrounding ambient air without causing any problem to the performance of the transformer then its normally reffered as Naturally Air Cooled transformer or simply air cooled transformer. However when the capacity of the transformer increases, the heat generated in the winding of the transformer is more and the ambient air normally is inadequate to cool the windings and maintain the performance of the transformer. Its because of this reason the transformer windings are submerged in an oil tank. It has been observed that the hydrogen ions present in oil help to maintain the temprature of the winding of the transformer and thus overall performance of transformer.

Minimum distance of air gap
TPS Class CT is used for transient performance (TP). TPS class Current Transformer has Low Leakage Flux and there is no limit for remanent flux) further there are also TPX,TPY and TPZ class CTs 1. TPX- No Limit for remanent flux due to nil air gap in the core 2. TPY - remanent flux does not exceeded 10 % due to less air gap in the core 3. TPZ- Having practically null remanent flux because there is large air gap is provide in the Core Er. Anil Prajapati, Protection Engineer,Jaipur RVPNL
